Python import os path=”/path/to/files/” for filename in os.listdir(path): prefix, num = filename[:-4].split(‘_’) num = num.zfill(4) new_filename = prefix + “_” + num + “.png” os.rename(os.path.join(path, filename), os.path.join(path, new_filename)) you could compile a list of valid filenames assuming that all files that start with “output_” and end with “.png” are valid files: l = [(x, “output” … Read more

Try to use a loop, let, and printf for the padding: a=1 for i in *.jpg; do new=$(printf “%04d.jpg” “$a”) #04 pad to length of 4 mv -i — “$i” “$new” let a=a+1 done using the -i flag prevents automatically overwriting existing files, and using — prevents mv from interpreting filenames with dashes as options.
